LOOSE-LEAF AND, SAMPLE-PAPER BINDER.

Application filed October l20, 1924. Serial No. 744,635.

To all whom t may concern:

Be vit known that I, HUBERT AUBURN, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in a Loose-Leaf and Sample-Paper Binder, of which the following is a specification,

An object of my invention is to provide a loose leaf binderof an improved construction for the reception of loose leaves or samples of paper.

Another object of my invention is to provide a device wherein the pages can be speedily and efficiently inserted and removed.

Another object of my invention is to provide a loose leaf binder the top Acover of which can be speedily removed.

Another object of my invention is to provide a device that does not require key to loosen the top cover.

These and other objects are `attained by the means described herein and shown in the accompanying drawings, -in which:

F ig. 1 is a fragmental perspective view of a loose leaf binder having lembodied therein a device of my invention.

F ig. 2 is ra sectional view on line 2-2 of Fig. 1.

The device of my invention consists of a pair of telescoping binder or angle plates 5 and 6 that together form a back for the binder. The plate 5 has mounted on it a plurality of pins 8. The pins 8 are adapted toenter the bores-12 in the hollow posts or tubes 9 mounted on the other plate 6. The hollow posts 9 and pins 8 are in axial alignment and together form telescoping posts. Loose leaves of a book or loose samples of paper 11 are perforated, such perforations being spaced in accordance with the position .of the posts so they may be received thereby. The loose leaves or samples of paper 11 have a slot 29 formed in them at their rear edge forv a purpose that will be eX- plained hereafter.

The side 7 of the plate has formed in it a depression 13. The head 16 of a screw 17 is normally received in this depression for locking the angle plates 5 and 6 upon one another. The threaded shank of screw 17 is received in an internally threaded sleeve 18. The lower end 19 ofthe sleeve 18 is bifurcated and the branches 2O and 21 so formed receive between them a lug 22. The

lug 22 is mounted on the horizont-al base 10 of the angle plate 6. A. pivot 23 connects branches 20 and 21 and lug 22. Sufficient space is provided between the top of the lug 22 and the bifurcation in the sleeve to permit the sleeve 18 to oscillate about the pivot 23.

The side 7 of angle plate 5 has formed in it an elongated perforation 25 having an enlarged portion 26 and a restricted *pois tion 24. rlhe depression 13 is concentric witlrthe restricted portion 24. The width of the restricted portion is substantially the same as the diameter of the shank of screw `17. rThe diameter of the enlarged portion of perforation 25 is slightly larger than the diameter of the head 16 of .thescrew. The head 16 will pass :through the enlarged portion of perforation 25 but .not through the restricted portion thereof. The shank :however may be moved longitudinally of the perforation 25 for lodging the screw head in the depression 1 3 and for removing .the screw head therefrom.

When it is desired to remove the top cover 2? of the binder, screw 1.7 is unscrewed until the head 16 of the screw is raised sufficiently `to permit movementof the sleeve and-screw about their pivotal mounting for t;

aligning the screu7 head with the enlarged portion 26 of perforation 25, whereupon the angle plate`5 may be moved relative to angle .plate 6.

It is readily evident that the invention .f

disclosed Vmay be applied to telescoping or nonftelescoping binders.

The slots 29 are Vformed in the sheets of paper 11 `to accommodate the pivotally mounted -sleeve and screw carried thereby.

The operation of my device is as follows:

l/Vhen lit is desired to open the binder screw '17 is rotated to elevate thelieadthereof from .the Idepression 13, whereupon the screw and sleeve are movedto the vposition shown in dotted lines, whereupon the head 16 of the screw may pass through the perforation 25. The angle pla-tes 5 and 6 may then be moved relatively to permit separation of said angle plates. The procedure is reversed for mounting the angle plates upon one ano-ther.

What I claim is:

1. In a device of the class described the combination of a pair of binder plates comprising posts, one of the plates having a perlll foration having an enlarged and a restricted portion, a screw having a head mounted on the other plate, 'the head of the screw being capable of oscillation through the perforation and of reciprocation through the enlarged portion of the perforation but incapable of reciprocation through the restricted portion thereof for `locking and unlocking the plates relative to one another.

2. in a device of the class described the combination of a pair of binder members comprising posts, one of the members having a perforation with a restricted portion in it, a reciprocable locking means pivotally mounted on the other member and reciprocable through the perforation in the first mentioned member for locking and unlocking the members relative to one another.

3. ln a device of the class described the combination of a. pair of binder members comprising posts, one of the members having a perforation having an enlarged and a restricted portion, the said one member having a depression surroundingrthe` restricte-d portion of the perforation, a reciprocable locking means mounted on the other member, the locking means comprising a screw having a threaded shank and a head, an internally threaded sleeve hingedly mounted on the second member and receiving the threaded shank, the head ofthe screw being capable of passing through the enlarged portion of the perforation but not through the restricted portion thereof, and normally seatedin the depression to lock the members together.

4t. In a device of the class described the combination of a pair of binder members, posts carried by the members, one of the members having a perforation having a re stricted-and an enlarged portion and hav' ing adepression surrounding the restricted portion, an internally threaded sleeve, a pivot connecting the sleeve and second binder member, a screw comprising a complementary threaded shank for engagement with the threads on the sleeve and a head, the screw head being capable of reciprocating through the enlarged portion of the perforation but not through the restricted portion thereof for locking and unlocking the Y members relative toy one another, the head of the screw being normally seated in the depression when the backs are locked together and movable into and from said depression by revolving same in the sleeve.

5. In a device of the class described the combination of a pair of binder members, posts, one member having a perforation having an enlarged and a restricted portion, a depression surrounding the restricted portion, loose leaves with perforations and a slot in them, the posts being adapted to receive the leaves by entering the'posts into the perforations in the leaves, an internally threaded sleeve pivotally mounted on the other member, a headed screw having a threaded shank mounted in the sleeve, the sleeve and screw together adapted for ljoint and relative movement for reciprocation of the head of the screw through the enlarged portion of the perforation but not through the restricted portion thereof and for lodg-A ing the screw in the restricted portion of the perforation, the slot in the loose leaves receiving the sleeve and screw, the screw, sleeve and binder members together forniing a lock whereby the binder members may be locked and unlocked relative to one another, the head of the screw being seated in the depression when the binder members are locked together.

6. ln a binder of the class described the combination of a pair of binder plates, one plate being provided with an elongated perVm foration enlarged at one end and restricted at the other, a pivotally mounted screw on the other binder plate for movement longitudinally of itself for passage through the enlarged portion of the perforation for permitting relative movement of the binder plates and for lodging in the. restricted portion of the perforation for securing the binder plates against relative movement.

hln a device of the class described the combination Vof a pair of binder plates comprising posts, one plate having an elongated opening therein and a locking member pivotally mounted on the other plate adapted for movement into and out of said opening and when extending into said opening adapted for movement longitudinally of said opening to positions for locking and unlocking the plates upon one another.

In testimony whereof, I have hereunto subscribed my name this 15th day of October, 1924.

HUBERT AUBURN.
